This video doorbell actually works as described. I almost love it!
Here is the trouble.... if you live in a place where the outside temperature is bellow zero degrees Celsius for period of time... like a Canadian winter, you can not expect the battery to hold a charge nor can you expect the attached doorbell wires to keep it charged.
This is very disappointing... as winter lasts a few months around here with means weekly taking off the mount, disconnecting the doorbell wires and connecting it to a charger. Not a big deal except for the fact that it is cold outside... at times too cold to be wanting to be fiddling with those doorbell screws on the back.
This is enough to cause me to search out a replacement with an easily removable battery - with is a bummer as the Ring App and system is super fantastic. Would not purchase again.
